KANSAS CITY • A Kirkwood man who is among six people accused of sexually trafficking a southwestern Missouri woman is scheduled to change his not guilty plea on Tuesday, two weeks after a federal prosecutor said she wouldn't present evidence that he tried to hire a hit man to kill her.

Bradley Cook, 33, is facing seven federal counts in Missouri's Western District, five of which involve claims that he tried to hire someone to kill his accuser while he was being held in a federal detention facility in Leavenworth, Kan. Prosecutors also have alleged in court documents that he tried to hire a hit man to kill Assistant U.S. Attorney Cynthia Cordes.

Cook's lawyer, Carter Collins Law, acknowledged Tuesday's change-of-plea hearing but didn't comment further.

Cook is facing conspiracy and sex trafficking charges involving a woman who said she was a teenager when she moved into the rural Lebanon, Mo., trailer of co-defendant Edward Bagley and his wife, Marilyn, who also has been charged. The accuser said she was a sex slave for years.

Cook also is charged with use of an interstate facility to facilitate unlawful activity, attempted tampering with a victim, attempted tampering with a witness, use of an interstate facility in commission of murder for hire and attempted witness retaliation. Each of those crimes carries a maximum sentence of 10 to 30 years in prison.

Prosecutors alleged in court documents in January that Cook tried to hire someone to kill the victim and Cordes, the office's top human trafficking prosecutor, late last year. Last month, U.S. Magistrate Robert Larsen ruled that evidence of the plot against Cordes could not be presented at Cook's trial unless the prosecutor removed herself.

Cordes responded she would continue prosecuting the case and would not present evidence of the alleged plot against her.

In Missouri's Eastern District, Cook faces a charge of owning guns while being a marijuana user.

Two other defendants, James Noel and Dennis Henry, have pleaded guilty of conspiracy to commit sex trafficking by force, fraud or coercion.

The U.S. attorney's office in Kansas City declined to comment about the case.

Cook's plea deal would leave only Michael Stokes, 63, and the Bagleys as defendants. Stokes is charged with conspiracy, sex trafficking by fraud, force or coercion and use of an interstate facility to facilitate unlawful activity.

The Bagleys face the same three charges, in addition to forced labor trafficking and document servitude. Edward Bagley is also charged with use of an interstate facility for enticement, enticement to travel for sexual activity, transportation for sexual activity and possession of a firearm in furtherance of a crime of violence.
